Case	12/12	10/12	12/12	8/12	8/12	12/12	9/12	8/12	82.3%
Control	12/12	12/12	12/12	10/12	12/12	12/12	10/12	9/12	92.7%
Total	100%	91.6%	100%	75.0%	83.3%	100%	79.2%	70.8%	87.5%

This table presents the number of correct detections by the IDEEA monitor over the number of total trials ($n$ = 6 cases and 6 controls). The 10.4% difference in accuracy in controls versus cases (92.7% versus 82.3%) was statistically significant (chi-square test, $P$ =.029).
